Bermuda lawns require 8 hours or more of sunshine each day. The limbs on my trees were spreading out providing too much shade over parts of my lawn, so I trimmed the trees to increase the sun exposure to those parts of the lawn.
I just discovered your channel. Very good information. I have just started to develop my own lawn care program, lots of trials and errors. When we bought our house 3 seasons ago (McKenny TX) the front yard was full of weeds, specially crabgrass and Poa annua. This season 2021, both the front and back are weed free. I will trim one of my trees per your suggestion to have the lawn in that area thicken out. Keep up your work sir.
